Yes, AFAIK also, no other fw (including sg/my) of any vintage was ever able to see TH jcv, for that you need TH fw.

But I see some guy says it worked on his nuvi 205W SG/MY firmware...
Maybe it does on a sg/my 205w with older fw, or maybe the guy was mistaken. Maybe Aek can say if it's possible unmodded for that unit, but that info still won't help you with 1455CHN....

Is there any workaround for other devices with SG/MY firmware to fit Thai JCV?
Not unless you are prepared to risk flashing to TH fw. You could try with your original boot bin and don't power off, then if problems flash back to full CHN fw..

I am looking to flash my 1455 CHN firmware to a SG/MY one. Is it worth the hassle to do that, just for a JUNCTION VIEW?
As we can see from this diagram(credit to aekhong), it seems like SG/MY firmware is the 'best' one in terms of JCV compatibility? ...
SG/MY could never see TH jcv in any case (afaik). Until recently I also thought that the info in that diagram was still current but see [Only registered and activated users can see links. ] where it seems aekhong is saying it's no longer true with newer units/fw.
